Sensor size mostly helps the signal to noise ratio and matching up to 
existing optics/format mentality. Prosumer cameras with small 5MP 
chips need custom optics with MTF's that will resolve the 3 micron 
well sites, which is the limit for the penetration of blue light.

I agree with Karen. Dollar for dollar, the Sigma will blow away all 
the 6 MP cameras until Sigma comes out with their rumored full frame 
version, which should perform as well as any 33-50 MP monochip, which 
don't yet exist.

Letting glass dictate the camera can be backwards in some 
applications.

It was, but now with the X3 chips, Foveon is inside the Sigma, and 
it's better.

Agreed. Ask any Pro Videographer if he's rather use a single chip or 
3 chip camrera for better color response. No contest. Until the X3 
chip, it wasn't feasible. This is revolutionary technology.


More later....
